I \J I A \\\\\\\.,.V\\\. \J 4I mx //l/l NI W -IIIIHMIIIIHNIIII IIIIIIIII Il I rather 'what may be termed the pounding 'of the car on theside bearingroller, induces indentations into the soft metal track ofthe roller, when the latter is made of east steel or malleable iron,so'that it is desirable to' face Athe track upon which the roller rideswith a steel plate harder than the materials of the casting.

I make the rocker plate l2 of steel, an cause it not only to perform thefunction of bringing the roller to its normal position, but also to actas theV facing' plate for the bearing and thus I salve expense in thecost of the bearing over otherdevices which seek to accomplish the samepurposes.

The cost of labor in making my bearing is the minimum of any otherbearing havingl anythino like the same or equivalent merits, since thereis almost no labor 1n assembling the parts. The parts are simply and thebearing is finished.

In place of the rivet 9, I mayuse any other suitable means, such as aCotter pin, bolt, keyror other locking device with which to dam oii thehole through which the pin is inserted. f i

Should the bearinpry need repairsatany time, the rivet 9 is removed andthe pin driven out by any suitable tool, yinserted placed togetherandthe rivet 9 fastened,

through the hole f 16, thereby forcing *theL pin Sout 'of 'the housingyand thus freeing the roller and the plate. The rollers used in bearingsof this kindare usuallyv made very hard so as to stand Withoutdeformation. the pounding y that they receive in service.

In the side walls ot the boX of the casting 3, there are apertures 17and 18 at the sides of the housing, andl 19 and 2O rat the Theseapertures permit the free es-l cape of any dirt Oriol-eign matter thatmight happen to come Within the. box in the housing. Y

It is desirable that a ,rocker plate be made as Jthin as can be made,and yet suiiiciently stil' to prevent its being bent or distorted underthe load of the roller, for the reason that the thinner the plate, thelower its center of gravity and the.morerit acts in bringing the rollerto its own'center. And when the thickness of this plate isal largepercentage of the radius of the rollerfit seems to have much less effectto lturnA the roller to its normal position. "llhisfmzwbe due in part tothe extra inertia and resistance in moving itself, 'and further to thefact thatthe vcenterof gravity of thethicker .Weight to return theroller to its position.

It is desirable tov have the engaging 'pro-i jections which Ainterlockthe plate 12, and the casting 3 upon the casting and .have the holes inthe plate instead of having'projee lplate is higherv up, and as theplate rocks, lit passes vthrough L less vdistance .of travel,givingle'ssfnloment in proportion .to its normal tions on the plate andholes in the. casting, The plate 1s more sensitive 1n the arrange-`-ment' as I have `shown than the other Way.

It is, cheaper also to make-the projections of the interlocking means,betweenthe plate 12 and housingl 3 Ourthe casting 4and make the 'hole inthe plate.

I prefer to 'call the bottom of the houslng,` whereon rocks the plate12, La track face'` as Will be notlced in the claims.

What I claim is: 1. 'In a device of the class described, the combinationWith a housing of a bottom track surface with upwardly extending pro-v Ybox-like housinff' having at its bottom a a.

track surface and guideways in its lateral Walls,l of* a curved rockerplate resting upon said surface and provided with a series of recesses,and); weightreceiving roller resting upon the 'bon-care surface of saidplate,

traveling alon; r said rguideways and held` therein against upward'displacementisaid bottombeing provided with upwardly eX tendingprojections of a length not exceeding the thickness of the plate andadaptedV to lit loosely in said `recesses, respectively.

3. The combination with an. elongated box-like housing having at itsbottom ai track surface, of a curved rocker plate restl ing. on thatsurface and a Vroller resting` upon the rocker plate "and heldagainstu'p-t Ward displacement, the ond walls of the housing being cut-aWav at their lower sid-usf below -and beyond the upwardly curvedmargins of the rocker plate.
